Definitions

  • the present invention relates to a taste improver for selective improvement or lowering of unpleasant bitterness (Nigami), astringent taste (Sibumi), harsh taste Egumi), bitter taste (Shurenmi) caused by potassium salts, magnesium salts, calcium salts, and ammonium salts; a potassium salt taste improvement method using the taste improver; and the use of a water and/or ethanol vegetable extract of parsley, celery and/or celery seed and/or at least one of apigenin and a glycoside thereof as a taste improver in a foodstuff comprising at least 0.1 parts by weight of one or more of the above salts.
  • Table salt sodium chloride
  • table salt plays an important role in functions as exemplified by control of bodily internal water content, pH, and osmotic pressure, digestion of foods, absorption of nutrients, neurotransmission, muscle activity, or the like.
  • Table salt has a wide variety of roles in foodstuffs. Examples of such roles include enhancement of delicious taste or savoriness, imparting texture, retention of color, or the like. The effect on flavor of foodstuffs is great, and the addition of table salt enhances sweetness and delicious taste, and decreases unpleasant bitterness.
  • excessive intake of table salt is thought to increase the risk of occurrence of lifestyle-related diseases such as high blood pressure, kidney disease, heart disease, cancer, or the like.
  • table salt plays an important role in determination of quality of foodstuffs. Thus, savoriness is harmed and flavor is lost in a food or drink in which the utilized amount of table salt is simply decreased during flavoring and processing. For the development of low-salt foodstuffs, it is most important to attain both robust saltiness and delicious flavor even though table salt content has been reduced. There is a strong need to develop technology to realize such attainment.
  • non-table salt substance that has saltiness By addition of a non-table salt substance that has saltiness, it is possible to make up for the low saltiness that occurs when table salt is decreased.
  • substances that have saltiness include potassium salts such as potassium chloride or the like, magnesium salts such as magnesium chloride or the like, calcium salts such as calcium chloride or the like, and ammonium salts such as ammonium chloride or the like. In comparison to sodium chloride, these substances are characterized by having weak saltiness and having unpleasant bitterness, astringent taste, harsh taste, bitter taste, or the like.
